The Nuclear Spectroscopic Telescope Array Mission
(NuSTAR) is an X-ray mission with the first focusing optics for hard
X-rays (above 10 keV).NuStar is led by Caltech and managed by JPL for NASA's Science Mission Directorate.
It was launched on June 13, 2012 from a Pegasus XL rocket
near the Kwajalein Atoll, and placed in a low-inclination low-Earth orbit.
Initially deployed for a two year mission, it continues to collect data.
Lifetime : July 2012–present
Energy Range : 3–79 keV
Special Features : the first hard X-ray focusing optics
at higher X-ray energies.
Two coalined Conical Wolter-I mirrors focusing X-ray onto two Focal Plane Module
Detectors (FPMA an FPMB).
The mirrors consists of 133 concentric conical multi-layer mirror shells.
The mirror shells are coated with Pt/SiC and W/Si multilayers atop thin sheets of flexible glass,
with graphite spacers between nested layers.
They are mounted on a mast that was extented in space to provide a focal lenght of 10 m.
A Metrology system of two lasers on the optics end that are pointed at three light-sensing detectors at the detector end
of the telescope.
Angular resolution: 58" (HPD), 18" (FWHM)
FoV (50% resp.): 10' at 10 keV, 6' at 68 keV
The FPM detectors are Cadium-Zinc-Telluride (CdZnTe) rectangular crystals, 20 x 20 x 2 mm
in size, divided into 32 x 32 gridded arrays of pixels.
The detector privides an energy Resolution (FWHM): 400 eV at 10 keV, 900 eV at 68 keV
The detectors are surrounded by Cesiun Iodide (CsI) crystals as active anti-coincidence detectors to
register and reject background from high energy photons and cosmic
rays entering the detector from off-axis directions.
conducted a survey of black holes, monitor the mechanisms of their growth, and
the radiation from infalling matter
study processes at the core of jet structures around super-massive black holes
map remnants of recent stellar explosions (novae, supernovae, and hypernovae)
study compact stellar remnants (black holes, neutron stars, and white dwarf stars)
provide insight into the solar corona and giant flares
